From Radial Engineering
The direct box that does it all
The JDV makes no compromises on available features or audio quality, opting instead to provide anything you could ever ask of a high-performance DI box. Designed for studio recording or pro-touring applications, the JDV provides exceptional headroom with massive 30-Volt internal rails, resulting in virtually zero distortion and producing an incredibly transparent and natural representation of your instrument. It has two inputs which can be individually selected or blended together and phase-aligned, with the ability to handle condenser mic's, piezo transducers, and the outputs of effectively any instrument. The balanced output can be set to mic or line-level, allowing you to bypass an additional preamp and connect directly to a recording interface for pristine studio recordings.
Features
Front Panel:
- Level A - Fully variable potentiometer, used to set the input sensitivity for channel-A
- Drag Control - Switches input impedance from 10 meg Ohm for piezos to DRAG control for magnetic pickups
- 48V - LED indicator lets you know 48V phantom power is activated
- HPF - Eliminates excessive low frequency mud that can cause resonance and acoustic feedback on stage
- A/B - Channel selector switch, toggles between A and B inputs with LED status indicators
- Load - Switches input impedance from 10 meg Ohm for piezo transducers to 220k Ohm for magnetic pickups
- SIG/OVD - LEDs show signal presence and if you are exceeding the maximum input level
- Phazer - Adjusts the relative phase between channel A and B to time align fundamentals for a more natural sound
Rear Panel:
- Power - Locking 4-pin XLR power connection for external power supply
- Output - Balanced XLR connects to the PA and recording system
- 180º - Inverts the signal polarity by flipping pin-2 and pin-3 on the XLR output
- Ground Lift - Disconnects pin-1 at the XLR out. Helps reduce noise caused by ground loops
- Isolation - Introduces an isolation transformer into the XLR signal path to help eliminate hum and buzz caused by ground loops
- +20dB - Extra high output or direct recording
- Tuner Out - Hi-Z always-on 1/4" output used to connect tuner
- Thru - Unbalanced 1/4" thru-put used to feed the stage amp
- 1/4" Inputs - Unbalanced 1/4" input jacks used to connect instruments to the JDV
- JR-2 - Connection point for the optional JR-2 remote footswitch
- Mic In - Balanced 1/4" TRS input for condensor or dynamic microphone
Side Panel:
- Mic 48V Phantom - Turns on the 48V phantom power at the MIC IN
- Blend A+B in - Combines input-A with input-B and lets you mix the two sources using the front panel level controls
- Aux Out/Direct - Lets you introduce an isolation transformer into the stage amp output signal path to reduce hum and buzz caused by ground loops
